Seeing multiple problems with this release...

1.  Nasty oops when rebooting into -mm2.  Then I rebooted back into -mm1 and it 
happened again - so I cold booted this time and the problem went away.

2. Notice above how the sky2 driver is being bailed out:

ACPI: PCI Interrupt 0000:04:00.0[A] -> GSI 17 (level, low) -> IRQ 177
sky2 Cannot find PowerManagement capability, aborting.
sky2: probe of 0000:04:00.0 failed with error -5

This has happened a number of times in the last few days, and I suspect is 
unrelated to the oops that followed above.

This driver worked fine in 2.6.15-rc5-mm3, and seems to work OK when built as a 
module.  But most of the time (not all the time) it doesn't like being 
statically built in and fails with the above error.  Changes to this driver have 
been fairly small lately so I'm not sure if it's the driver or something else 
like ACPI that is the root cause.

3.  The boot up process with -mm2 was pretty lengthy, I had two periods of time 
when the whole system just came to a crawl, first time was when starting cups, 
and it came back to life and continued booting about 30s later.  Next when 
starting hpijs it didn't come to life at all and I had to reboot.  No output to 
the console for either, unfortunately.

Back on -mm1 for now, box has only got an PCI graphics card and I'm not running 
X, DRM or AGP, so by all accounts -mm1 is OK for me ;-)
